It's difficult to say what binding would suit without knowing height weight etc. I'm assume you'll be using the skis for pow and maybe some all mountain too and you're a level 3/3+ skier.Until I/we know this I difficult to say what kind of din range you need.
Bindings costing ~$150 new and which are season are likely to be entry level bindings/junior bindings (similar to the axiums), which might not be appropriate for you height/weight/skiing style. However you may be able to pick up some more suitable bindings which are new, but from past seasons here -
